Nintendo 64 RGB upgrade – Compatible consoles only!

Available now (handled by our partners BetaGamma Computing in Greece). Please allow for shipping and processing delays due to slow post in Europe and technical issues at the Greek post office. UK customers MUST e-mail us first about ANY mod work (except NI).

All repair/upgrade work is carried out subject to our terms and conditions. Once you have placed your order, details of where to ship your hardware will be sent to your e-mail address. Prices do NOT include return postage.

Have your compatible Nintendo 64 console professionally upgraded to RGB using the best available RGB amp (included in the price of the upgrade). We now perform this upgrade using the newest THS7374 based RGB amps. Furthermore, if you need CSYNC (clean composite sync) output, we will add that to your console too.

Note – You MUST check that your console is compatible with this upgrade before ordering it. Only NTSC consoles with NS1,NUJ1 or NUS-001 serial numbers are compatible, but the only way to know for sure is to open your console. Please check this page for more help determining if your machine is compatible. If you send us a console that is incompatible we will unfortunately have to charge you for return postage. If you have previously had your compatible N64 RGB upgraded and the picture is too dark, we can also fix/upgrade your console to the new RGB amp. Once your console is upgraded, you should use a Super Nintendo NTSC RGB SCART cable for use with it. You can purchase a suitable cable here.

About the low pass filter

Our new amps include the option to turn off the low pass filter. There is considerable debate as to what is the best option for this and no clear right or wrong answer. Many people believe that if you’re using the console predominantly with a scaler like the OSSC or XRGB Mini you should disable or turn off the low pass filter, otherwise you should leave it on. Turning off the filter can give a slightly sharper image but can also introduce other problems, such as picture noise.

About Csync (clean sync) output

Our newest model of amp allows for either TTL or 75 ohm composite sync output.

The standard (as output by the Super Nintendo) is TTL sync. This requires a cable with an attenuation resistor installed. Using this option combined with a cable that does NOT have the resistor installed can damage your equipment. Most cable manufacturers are now aware of this and will include the resistor in their cables. However if you have an older cable it may not include the resistor as this was not widely known about in the past.

If you choose the 75 ohm output option above then the console will output 75 ohm sync at source and will NOT work with a cable that has a resistor inside it.

If you have a csync/clean sync cable for your console already and you include it with your system, we’ll check it for you and configure the upgrade accordingly.

If you need a new Csync cable to use with your upgraded console, you can use the NTSC SNES PackAPunch cable available here. Choose the “CSYNC TTL 2.5 Volt” option when configuring the cable, then choose 75 ohm output option above when buying the upgrade. Since your console will then output 75ohm sync you do NOT need a cable that is corrected for this, so the TTL cable is the right one.

Note – Normally if we’re upgrading you from an old-style amp upgrade to one of our new ones, we’ll remove the old one free of charge. However, if it was very badly installed (e.g using hot glue or similar) then we reserve the right to charge a fee to remove it and clean your console. We will notify you before starting work if this is the case.
